Martin

Martin was a student briefly at Pearl Bailey High School that Snot tries to use as cover during bullying season in "Scents and Sensei-bility". But when Mertz is attracted to Martin's apparent weakness, he and Steve find that Martin is more than capable of taking care of himself by beating up the bully.

They discover that he is a karate master from the Dojo Biden, but also find out that he keeps getting kicked out of school for fighting as he is taken away in handcuffs. As a result of getting kicked out of school, he also can't read.

He attends Steve and his friends party for the unpopular kids in "The Unincludeds".

Martin is voiced by DJ Qualls.
